录音原文
技巧点拨
Saving Wild Birds
Part A:
two problems
Hu
Xiao
is
a
senior
high
school
student
who
shows
a
great
interest
in wildlife protection. Today he has got a good
chance
to interview a volunteer, Alice
Brown, from IBRRC.
HX: Hello Alice. I’m
so interested in your work saving birds!
What
do
you
think
is
the
most
difficult
part
of
your
work?
AB:
Well
…
I
suppose
it’s
saving
wild
birds
covered
in
oil.
That’s the most
difficult of all.
HX: How
does that happen?
AB:
The
oil
comes
from
boats.
It
floats
on
the
water
and
covers the bird’s
feathers when they swim through it.
HX: That sounds terrible. What do you
do about it?
AB: The first thing we do
is make sure the bird hasn’t eaten
too
much
oil.
When
a
bird’s
covered
in
oil,
it
tries
to
clean
itself with its beak. As it does so, the bird eats
some
oil and becomes sick.
HX: Oh dear! Do the birds always die?
AB:
Sometimes
…
but
we
try
to
save
them.
Birds
use
their
feathers
like
a
raincoat
to
keep
out
cold
water.
When
feathers are covered in
oil, they stick together
and a bird’s
skin
gets
cold
in
the
water.
So
without
help
the
bird
would
die of cold!
Part B: the
solution
HX: What do you do with those
birds?
AB:
First,
we
comfort
a
bird
by
feeding
it
and
keeping
it
warm. Then we clean it.
We rub the bird very carefully.
We use
warm water and a little soap and work quickly as
the birds hate being touched.
HX: Is this a difficult job?
AB: Yes, because it’s very important to
do the job quickly.
HX: What
happens after that?
AB: The birds are
kept warm and given a rest.
HX: I
suppose after that they want to touch their
feathers with
their beaks.
AB: Yes, they do. Birds produce a
natural oil in their tails and
put this
over their feathers until they feel better.
看看这些图画，预测你将要听到什么内容，
预先读书中的
Ex3
的选项可以预知这些重
点。如
raincoat
,
cold,
water,
flows,
stick,
together, get, cold,
may, eat, oil, get, sick
带着
预习的内容去听，能够达到事半功倍的
效果会。
Listen to B
and complete Exercise 4
对于稍有难度的
Exercise
4
来说，更应该在听力之
前阅读这两个题目，
< br>然后根据你对
Ex2
和
Exercise
3
的掌握情况，<
/p>
和文章中的一些事实细节回答这两个
题目。注意回答出
h
ow
。关键此为，
comfort
，
clean
。
听力小技巧：
How-question?
主要提
问：年龄、距离、速度、价格、数量等；
说话人对事物的反应，动作的方式等。问题的主
要
形式如下：
?
How old
is the man
？
?
How long does it take them to get there
if they
take
plane
？
?
How did the man go to
Japan
？
?
How much did the man pay for the
dress
？
?
How did they feel about the
train
？
?
关于年龄、
距离、
速度等一般要进行简单的
运算。
考生除了要听清楚数字外，还要注意百分数、倍数
等的数
量词，如：
double
，
half<
/p>
，
dozen
，
couple
，
thirty
percent
，
three times
，
century
，
etc.?
HX: Thank you.
I’ve learned a lot.
AB: Not
at all. It’s been my pleasure.
